Question

(3 underroot 45 -underroot 125) +( underroot 200- underroot 50) simplify it​

Answer 1

$3 \sqrt{45} - \sqrt{125} + \sqrt{200} - \sqrt{50}$

$= 3 \sqrt{5 \times 3 \times 3} - \sqrt{5 \times 5 \times 5} - { \sqrt{5 \times 8 \times 5} } + \sqrt{5 \times 2 \times 5}$

$3 \times 3 \sqrt{5} - 5 \sqrt{5} + 5 \sqrt{2 \times 2 \times 2} - \sqrt{5 \times 2 \times 5}$

$9 \sqrt{5} - 5 \sqrt{5} + 5 \times 2 \sqrt{2} - 5 \sqrt{2}$

$= 9 \sqrt{5} - 5 \sqrt{5} + 10 \sqrt{2} - 5 \sqrt{2} \\ = 4 \sqrt{5} - 5 \sqrt{2}$
